Nba live 08 PS3-control settings-help pls!

Hy guys! I just bought my FIRST console a PS3! I ordered nba live 2008 but until my game will arive i download the demo version from playstation store.The game look amazing(i was used with pc games) but i can't figure how the change my controls.my question is, is this a problem because it's a demo version?(and it don't allow to change the default controls) ?is this a problem with the nba live 08 in general, or is this a problem with all the PS3 games? I simply can't play with their configuration.....
